PLOW.

SPECIFICATION formingpart of Letters Patent No. 229,954, dated July 13,1880.

Application filed April 5, 1880.

To all whom it may concern Be it known that I, JEROME I. OAsE, a citizenof the United States, residing at Racine, in the county of Racine andState of Wisconsin, have invented certain new and useful Improvements inFlows; and I do hereby declare the following to be a full, clear, andexact de scription of the invention, such as will enable others skilledin the art to which it appertains ro to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in wrought-metal plows in which therear brace between the landside and mold-board, at the bottom of theplow, passes through an eye in the lower end of the curved metalstandard or plow-beam in such manner that the said standard or beam maybe adjusted laterally on said brace; and the objects of my improvementsare to brace the plow-beamin such manner as to aid in resisting thestrain of the draft on the connection of the standard or beam to thebrace. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of a plowembodying my invention, partly broken away.

0 Fig.2 is a bottom plan, seen from below.

The same reference-letter indicates the same part in the differentfigures of the drawings.

A is the mold-board, B the share, 0 the landsidc-bar, D the beam, E thehandles, F the 3 5 handle-braces, and G the rear bottom brace, of anordinary wrought-metal plow of that class in which the standard or beamis curved so as to stand clear of the top of the mold-board, and has aneye, d, at its lower end, through 0 which eye the brace G passes, so asto permit of adjusting the beam D laterally thereon, and being retainedafter adjustment by a setscrew, g.

(No model.)

D is an extension of the lower end of the beam D, and has a transverseslot, h, in its end, 5 through which a bolt, it, passes to secure it tothe share B. Lugs I project laterally from the extension D, and haveslots t", through which bolts 2' t' pass and respectively through themold-board and share. The extension D, bolted to the mold-board andshare, forms an effectual brace andstrengthens the connect ion of thebeam to the brace Gr, so that the heavy "strain to which it is subjectedin operation will not strain nor twist the brace G nor tear the beamloose from it, and by loosening the nuts on the bolts h it therespective slots through which they pass will permit of lateraladjustment of the beam in the evident manner.

The extension D may be constructed in va- 6o rious forms, and boltedalone to the moldboard, to the share, or to any fixed plate or frogbeneath the plow, my claim not being limited to its particular form, orto the particular manner of its attachment to the moldboard and share;but

What I claim as new, and desire to secure by Letters Patent, is

1. In a plow, the extension D, adapted to brace the beam D, incombination with the 7o brace G, to which the beam is attached andadapted to be laterally adjusted thereon, substantially as and for thepurpose specified.

2., In combination with the mold-board and landside of a plow and acurved beam having an eye by which it is made laterally adjustable onthe brace G, the extension I), having transverse slots through whichbolts pass to secure it to the mold-board, substantially as and for thepurpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
